The present invention relates to brushing machines for circular objects, such as bilged barrels and straight sided drums, and an object of the invention is to provide a brushing machine which will efiectively brush the entire outside of a circular object, irrespective of the size and shape of the object within certain limits and without requiring any special adjustment of the machine'for articles of different shapes and sizes so that the machine may work upon differently sized and'sha'ped objects or bodies indiscriminatelye fed to it., c

To these and other ends, the invention r consists of certain parts and combinations ofparts all of which will be hereinafter described: the novel features being pointed out in the appended claims.

Fig. 5 is a fragmentary plan view.

The present invention contemplates the provision of a machine which will brush the side and ends of cylindrical or circular objects, such as straight sided drums and bilged barrels, irrespective of their sizes and shapes within certain limits. 1

In the illustrated embodiment of the invention, there is provided a main frame comprising, in this instance, four uprights 1 embedded at their lower ends in a cement base 2 and connected at their upper ends by two horizontal end pieces 3, the end pieces in turn being connected by two side pieces 4. At the lower part of the frame is arranged a Work support which, in this instance, is constructed to impart to the body 5 a rotary motion and which preferably also may be tilted to. one side to receive an object. and to the opposite side to discharge an object. To this end, this Work support may comprise two shafts 6 journalled at 7 on frani'epieces'l-O and each carrying a pair. of

spaced rollers 8, the shafts being spaced apart so that the object 5 to be cleaned rests on the two rollers of each shaft.- Oneach' of the shafts 6 may be arranged a gear 9, these two gears meshing with a gear 11' arranged to turn on a rock shaft 12 to which the frame pieces -10"suppo-rting the shaft 6 are'secured; l /founted to turn with the gear 11 is a large gear 13 Which in turn is geared to the motor 1 1 so that, through the motor,

the two shaftsG may be rotated to effect the rotation of thecircula'r object 5. V

The shaft,12-1s made to oscillate or rock in order that the work support may be swung inone direction t'o-receive a circular object and in the opposite dzrectionto' disch'a-r 'e' this obie ct This rockin of the work w i. a a b support maybe effectedthrough a lever 15 rigid wi'tl'rthe rock shaft 12 and connected 7 by a link 18 with an operating lever '17, pivoted at. 18,'to the frame of the machine and carryi'ng'a pawl '17, for cooperating With a rack '17. c i

With the end in view of facilitating the discharge of the object from the support, a rigid intake skid or conveyor 19 has a lever 20 pivoted thereto at 21, said lever extending from the end of the skid over the adjacent shaft 6 between the two rollers thereon, so

that, when the work support is moved to dis charge the objectonto the discharge skid or conveyor 21", the shaft 6 will engage the lever 20'and move the latter to discharge theob ject onto the discharge skid 21.

The cleaning of the circular wall of the object is, in this instance, efiected' by a rotary brush" 22 of cylindrical formation. brush may'bepartially enclosed in a housing 23 from-which the lower edge of the brush projects and may be supportedin the housing by a shaft'2'4t', one end of which projects from the housing at 25 and carries a pulley with which a belt 26 engages. This belt also engages a pulley on a motor shaft 27 of a motor'28 whi'ch is supported'on the housing 23 preferably at or near the center of the latter. V

The supporting means for the brush permits the "brus'hnot'only to adapt itself to This objects of different diameters with certa-in.

limits, but also to adapt itself to circular ob- J jec'ts of dihferent shapes such as bilged barrel's or st'rai'g'ht sided drums." The support.

V izing mechanism Preferably also, each pair of links is sus pended eccentrically from one of two rock shafts 32 or 33, the rock shafts having for this purpose each two arms 34 extending horizontally therefrom and pivotally connected at 35 to the links 29.

These rock shafts form part of an equalalso comprising, preferably, arms 36 depending from the rock shafts 32 and 33 and connected by links 37 and 33 with two arms 39 and 40 extending in opposite directions from a rock shaft 41. It is apparent that with this arrangement, if either end of the brush 22 is elevated the other end of the brush will be depressed. This permits the cylindrical brush to be rocked over the surface of a bilged barrel or body 5. The manual control of the brush may be effected by extending an arm 42 laterally from the casing 23 and rigid therewith, this arm being moved manually to swing the brush 22 in an axial direction or being moved up and down or laterally to cause the brush to rock about an axis mid way between its ends. The manner in which the brush is suspended through the links causes the two ends of the brush to counterbalance each other so that the movement of i the brush through the handle 42 does not impose upon the operative any material effort.

With the end in view of adjusting the axis of rotation of the brush toward and from the axis of rotation'of the circular object to accommodate quickly the machine to bodies of different diameters, a novel adjustment is provided comprising, in this instance, a

swinging member 43 mounted to turn about an axis 44 on the frame oft-he machine and supporting the pivot 41 of the double arm member 39 and 40. On the shaft 44 of this member is an arm 45 to which a link 46 is pivoted at 47, said link also being pivoted at 48 to a lever 49 which is in turn pivoted at 50 to the frame of the machine and which carries a manually operatablc pawl 51 adapted to cooperate with the rack or segment 52. Also supported by the shaft 44 is an arm 53 from which is suspended a counter-balance weight 54. The movement of the lever 49 in either direction from the position shown in Fig, 1 tends to shift the pivot 41, and in shifting said pivot turns the shafts 32 and 33 through the links 37 and 38, thus raising or lowering the housing 23 through the suspension rods 29, depending upon the direction in which the lever 49 is moved. The count-erbalancing weight 54 tends to hold the housing 23 with the brush in any position to which it may be adjusted, and the rack 52 effectively locks it in this position. I V

The cleaning of the ends of the object may be effected preferably by four brushes, two operating on each end of the object. One of thesebrushes 55 isof cylindrical formation and cooperates with the major portion of one end of the object, its axis of rotation being at right angles to the axis of rotation of the object. Theotherof these brushes 56 covers a smaller area and is designed to cooperate with flanges or chimes on the ends of the object, its axis of rotation being at an oblique angle to the axis of rotation of the brush 55. The brushes 55 and 56 are mounted respectively in housings 57 and 58, both secured in fixed relation, in this instance, to a movable frame of which there are two, one at each end of the object. Each movable frame 59 may be mounted to swing about an axis extending transversely of the axis of rotation of the object and situated above the object. One of these frames is mounted to turn on a shaft 60, while the other is mounted to turn on the shaft 33, hereinbefore mentioned, the frames depending from said shafts and supporting the brush housings 57 and 58 at their lower ends. The driving of the two brushes on each frame 59 may be effected by a single motor 61 on each frame having at its opposite ends two pulleys 62 and 63. The pulley (52 connects by a belt 64 with a pulley 65 on the shaft 65 of the rotary brush 55, whereas the pulley 63 connects by a belt 66 with a pulley 67 on a shaft 67 of the brush 56.

. With the end in view of effecting the movements of the two pairs of brushes simultaneously toward or from the opposite ends of the object 5, means is provided com prising preferably a lever 68 pivoted at 69 and connected by a link 70 to one of the swinging frames 59. This swinging frame 59 has a lateral arm 71 t'o which is pivoted at 172 a link 73. The latter in turn is pivoted at 74 to a lever 75 which is pivoted on the cross piece 3 at 76 and through an adjustable link 77 connects with the other swinging frame 59. Movement of the lever 68 in one direction simultaneously moves both pairs of brushes 55 and 56 toward the opposite ends of the body 5 and movement of said lever 68 in the opposite direction simultaneously moves both pairs of brushes 55 and 56 away from the opposite endsof the bodv 5. The swinging frames 59 may also be employed as guides for confining the movement of the housing 23 carrying the brush22 to a vertical direction and to this end each of. the swinging members 59 is provided with a vertical slot 78. In one of these slots, the controllinglever 42 operates, While in the other '23 line with guided. 1
